After more than half a century on the market, Darvon (propoxyphene) was pulled from the U.S. market. Why? Because studies have shown an increased risk of heart arrhythmias, even in patients without heart problems.

Some estimate that Darvon, manufactured by Xanodyne Pharmaceuticals Inc., has killed at least 1,000 people in the U.S. after using propoxyphene since 2005, according to the Los Angeles Times.

The Food and Drug Administration estimate that Darvon has been used by 10 million people in 2009, with most of them receiving the drug in combination with Darvocet (acetaminophen).

The FDA has known about negative Darvon side effects for years, but dragged their feet in taking the dangerous prescription drug off the market. Britain took Darvon off the market back in 2005.

Here is a list of some of the Darvon side effects:

  • Cardiac arrest
  • Coma
  • Convulsion
  • Dizziness
  • Diarrhea
  • Drug toxicity
  • Nausea
  • Respiratory arrest
  • Vomiting

To give you an idea on how lethal Darvon can be, here is an excerpt from a Darvon user’s experience:

“[I] was first given this for my chronic neuro pain when doc did not want to give anything stronger. I had such a bad time with it I thought it was going to kill me and I only took 3 pills…”

If you or a loved one has suffered adverse side effects after taking Darvon, consult with a lawyer right away. Xanodyne Pharmaceuticals should be held accountable for manufacturing such a dangerous drug. Speak to a lawyer and see what legal options may be available to you or your loved one.
